Operation
Install properly and DO NOT use this product outside the recommended
operating pressure, temperature and other specification ranges.
Improper use may result in such hazards as damage to the product or
malfunctions which may lead to serious accidents. Local regulations
may restrict the use of this product to below the conditions quoted.
CAUTION
Take measures to prevent people from coming into direct contact with
product outlets. Failure to do so may result in burns or other injury from the
discharge of fluids.
CAUTION
Operate valve slowly and carefully. Opening or closing valves too quickly
may cause water hammer to occur, the impact of which could cause
damage to equipment.
CAUTION
To be performed after installation and before initial operation
Make sure to flush the piping to remove welding slag, metal powder and filings.
Make sure that flange bolts etc. are securely tightened before passing steam/
water through the SR.
When conducting the test operation, start with a low steam and water flow rate
and gradually increase the load to normal operating conditions.
If you start with a normal operating load at the outset and there is a leak
somewhere in the piping, there is a risk of steam or water blowing out.
Startup
Make sure that the cold water inlet valve (A) and hot water outlet valve (B) are open
before supplying waste steam to the SR. If waste steam is supplied while the cold
water inlet valve (A) and hot water outlet valve (B) are closed, the pressure inside the
coil will increase due to volume expansion, which could damage the cold water inlet
valve (A) and hot water outlet valve (B).
1. Make sure that the blow valve (C) in the base
of the SR is closed.
2. Open the cold water inlet valve (A) and the
hot water outlet valve (B), allowing water to
pass through the SR. In cases where either
TIC (temperature control of heated water) or
FIC (flow control of heated water) is used,
start up the controls.
3. Open the condensate outlet valve, if any.
4. Open the steam inlet valve, if any.
5. Startup the equipment to allow waste
steam to enter the SR.
Make sure that there are no abnormal
discharges from the exhaust outlet or
overflow outlet for exhaust pipe*, such as
blowing steam or condensate. If there is
condensate blowing, or an abnormal
sound or vibration, halt operation immediately.
The first time you operate the SR, or when operating with the condensate blow valve
(C) open, waste steam may be discharged to the atmosphere through the exhaust
outlet or overflow outlet for exhaust pipe* immediately after initiating operation, due to
the lack of pooled condensate in the base to create an airtight water seal over the
condensate outlet. (if steam blow stops shortly then everything is normal)
